Angular-walled carton



May 4, 1943. J. D. CLARKE ANGULAR WALLED CARTON I Filed June 26, 1939 x Patented May 4, 1943 UNITED STATE s PATENT orrica 4 Claims. (c1. 229-34) This invention relates to the construction of an angular-walled carton of paperboard or like material. The carton contemplated is particularly adapted for the display of merchandise for sales purposes, its design being such that it presents an attractive and pleasing appearance.

The main objects of the invention are to provide a carton of attractive and pleasing appearance which may easily be made by automatic machinery of the type with which most box manufacturers are equipped; to provide a box construction which will be low in cost of production both in respect of labor and material; to provide a box which may be collapsed to flat condition for shipment and storage purposes but which maybe quickly and easily set up to receptacle form and whlch when set up, will be effectively locked in such form; and in general, it is the object of the invention to provide an improved carton or box of the character indicated.

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawing wherein there is illustrated the bodying a selected form of the invention,

In the drawing:

Figure 1 is a plan ,ofia blank from which the improved box may be formed;

Figure 2 is a plan of the box but collapsed condition, suitable for storage, shipment and other purposes;

Figure 3 is a fragmentary perspective; of one end portion of the improved box structure;

Figure 4 is a perspective of the box in set-up condition;

Figure 5 is a section on 4; and

Figure 6 is a section on ure 5.

Referring now to the drawing, the box herein contemplated comprises inner and outer bottom walls In and II, respectively, outer side walls l2, l2, inner side walls l3, l3, outer end walls ll, l4, and inner end walls l5, IS. The various inner and. outer wall parts described are designated by the same reference numerals in the plan view of the blank, and it will be understood that the various wall parts are separated from each other by suitable crease or fold lines which facilitate bending of the various wall parts relative to each other to permit the blank to be set up into a box.

The inner bottom member In is provided with a flap l6 which is adapted to be adhesively united to the inner side wall l3 at the opposite side the line 55 of Figure the line 6-6 of Fig- Chicago, 111., a corpoof the box, the flap It being preferably secured to the outside of the inner wall l3 as clearly indicated in Figures 2 and 5. As shown in Figure 2, the blank has been fabricated into a collapsed tubular form, the same being folded to flat con- Idition by folding along one of the fold lines which construction of a box em- 7 in pre-fabricated folded condition,

is set upg. The outer end walls 'be foldedieupwardly into an upwardly and inseparates an outer side bottom wall II, and along the fold line which separates the oppositely disposed outer side wall l2 from its contiguous inner side wall IS. The combined width of the outer bottom wall and of one outer side wall is such as to equal the combined widths of the inner bottom wall, the two inner side walls and the other outer side walls. Hence the folding to flat condition is readily permitted.

The outer side walls l2, l2 are provided with end flaps ll, H which are adapted to be folded inwardly from the ends of the respective side walls from which they extend, said flaps being adapted to occupy an inclined position in a plane which extends inwardly and upwardly from approximately the end edges of the outer bottom member II at about the same angle that the outer side walls l2, l2 occupy relative to the plane of theouter bottom member when the box l4, l4, may then war'dly extending, position outside of and adjacent the foldedend flaps l1, and the inner end walls l5, l5 may then be folded downwardly and inwardly around said end flaps.

To retain the end walls It, and IS, in such the inner side walls l3, l3 are provlded gwith end extensions l8, l8 which project beyond the ends of the inner bottom member l0 and engage end extensions, l5a of said inner end walls l5 as best shown in Figures 5 and 6. It will be understood that in setting up the carton, the first step is to adjust the collapsed tubular form as shown in Figure 2 to position wherein the outer side walls l2, l2 extend upwardly and inwardly as shown in Figure 5, and the inner side walls l3, l3 depend substantially vertically. Hence, the end extensions l8, [8 of the said inner side walls ii! are in place before the end walls [4 and I5 are folded around the tongues l1, II. The opposite end portions of the inner endwalls l5, l5, however, may be tucked into position behind the ends of the said end extensions I8, or forced by said end extensions by springing the latter outwardly and permitting the same to snap inwardly in front of the inner end walls when the latter clear the free ends of said end extensions.

wall l2' from the outer an erected The inner bottom member III is also equipped with a pair of end flaps l9, I9, which are adapted to be folded upwardly from the ends of the inner bottom wall to occupy a substantially vertical position as best shown in Figure 6. Such end. flaps l9, l9 thus occupy a position relative to the outer end-walls \II and I which causes said end flaps I 9, I! to simulate, at the ends of the box, the appearance of the inner side walls. Thus, the box is given a symmetrical appearance, notwithstanding the indicated angular position of the inner end walls l5, IS.

The described structure involves no complicated cutting or folding operations and it may be easily and rapidly fabricated to the collapsed tubular condition illustrated in Figure 2. From such collapsed tubular condition the structure may be quickly and easily adjusted to set-up box form for receiving the content for which the box is furnished. The structure, in addition to providing'an attractive box, also provides a sturdy construction which will effectively protect the content against crushing or other injury.

In the foregoing description and in the appended claims, the reference to certain parts of the structur by the words sides" and ends is not intended to be limited to the long and short ends of a rectangular box construction, these terms being used only for purposes of clarity and explanation. Obviously, the structure may be re-arranged, for example, by supplying the tongues on the end walls I 4, l4 instead of on the side walls l2, l2, and the inner bottom ID as an extension of one or both of the end walls, l5, l5.

Other changes may also be made without departing from the spirit of the invention, the scope of which should be determined by referenc to the following claims, the same being construed as broadly as possible, consistent with the state of the art.

I claim:

1. A paper box having outer and inner bottom, side and end walls, the outermost side walls being inclined upwardly and inwardly from the periphery of the outer bottom wall, the inner side walls extending downwardly from the upper edges of said outer walls and being connected to the inner bottom wall, said outer side walls having end flaps folded inwardly and disposed in planes extending upwardly and inwardly from upwardly adjacent saidend walls.

2. A paper box having outer and inner bottom, side and end walls, the outermost side walls being inclined upwardly and inwardly from the periphery of the outer bottom wall, the inner side walls extending downwardly from the upper edges of said outer walls and being connected to the inner bottom wall, said outer side walls having end flaps folded inwardly and disposed in planes extending upwardly and inwardly from approximately the end edges of said outer bottom wall, said outer and inner end walls being folded around said inwardly folded flaps so as to cause said outer end walls to assume an upwardly and inwardly inclined position, and the inner bottom member having end flaps extending upwardly inside of said inner end walls so as to walls thereof.

3. A paper box having outer and inner, bottom, side and end walls, the outermost side and end walls being inclined upwardly and inwardly from the periphery of the outer bottom wall, the inner side walls extending downwardly between the upper edges of said outer side walls and the side edges of said inner bottom wall, said outer sid walls having end flaps folded inwardly and disposed in planes extending upwardly and inwardly from approximately the end edges of said outer bottom wall, said outer and inner end walls being folded around said inwardly folded flaps so as to support said outer end upper edges of said end walls, said end flaps constituting, in effect, inner end walls extending between th upper edges of said outer end walls and the end edges of said inner bottom wall.

4. A paper box having an inner and outer bottom, side and end walls, said outer side and end walls being inclined upwardly and inwardly from the outer edges of said outer bottom wall and said inner side walls depending from the upper end walls.
